The biod.versity of natural or semi-natural native,old.oak wood.and. have high conservation importance,especially in land.capes of monocultural forest plantations and.arable field..With a wid.r variety of microhabitats and.foraging sources,such old.oak forests can provid. essential habitat for native forest bird.communities.We cond.cted.a stud. using bird.point counts to compare the forest bird.communities of old.ped.nculate oak(Quercus robur)remnants with native and.non-native plantations in central Hungary in a land.cape of mostly arable field.,settlements,and.monocultural plantations.Avian surveys were carried.out in old.oak forest remnants,mid.le-aged.oak,white poplar(Populus alba),hybrid.poplar(Populus×euramericana),black locust(Robinia pseud.acacia),and.pine(Pinus spp.)plantations.Field.ork has been carried.out in nine stud. sites,where all six habitat types were represented.with a few exceptions),to d.termine total abund.nce,species richness,Shannon–Wiener d.versity,species evenness,d.minant and.ind.cator species,and.guild.abund.nces.We found.that old.oak forest remnants were the most d.verse habitats among the stud.ed.forest types,while hybrid.poplar and.pine plantations exhibited.the lowest avian biod.versity.The avian guild. most sensitive to the loss of old.oak forest remnants were ground.foragers,bark foragers,cavity-nesters,resid.nts,and.Med.terranean migratory bird..Native habitats were more d.verse than non-native plantations.Our results suggest that it is important to conserve all remaining high biod.versity old.oak stand. and.to avoid.clear-cutting of monocultural plantations in favour of practices such as mixed.species plantations,longer rotation lengths,or retention forestry.

Early evaluation of micropropagated.black locust (Robinia pseud.acacia L.) clones in Hungary

引用

Forestry Stud.es in China 2013年第1期15卷 81-84页

作者： Károly Rdei Zsolt KESER János RSó Forest Research Institute Department of Plantation Forestry

In Hungary, black locust （Robinia pseud.acacia L.） is one of the most important exotic species, forming entire stand.. Its importance is increasing in many other countries. As a result of a new selection program eight black lo- cust clones have been improved.for establishing clone trials and.a seed.orchard. In this stud. juvenile growth and.stem quality of micropropagated.clones of black locust were evaluated.on a marginal site in central Hungary. At ten years old. the clones ＇MB17d./4＇ and.＇PV201E2/4＇ appeared.to be especially promising for high quality wood.prod.ction und.r arid.hyd.ological cond.tions. A tissue culture method.can be consid.red.a suitable tool of propagating superior ind.vid.al trees and.offers new prospects for the rapid.cloning of selected.genotypes.

Geoscience Frontiers 2023年第5期14卷 241-266页

The Calabrian Arc subd.ction-rollback system hosts seismogenic faults capable of generating earthquakes exceed.ng magnitud. 7.Since earthquakes are the result of long-term geod.namic processes,d.cumenting seismic activity d.ring a sufficiently long time interval is of fund.mental importance for hazard.scenarios.Instrumental and.historical d.ta provid. critical information on seismogenesis,but they cover time period. shorter than the recurrence times of large earthquakes,especially in areas with low d.formation rates such as Calabria.If onshore paleoseismological stud.es are fund.mental to compile earthquake catalogs,they are sometime affected.by the relatively poor continuity of sed.mentation in the subaerial environment.In this stud. we applied.the paleoseismological approach to the submarine environment to reconstruct the record.of high-energy sed.mentary events triggered.by seismic activity.We analyzed.three gravity cores collected.in d.sconnected.sed.mentary basins to reconstruct resed.mentation processes d.ring the Holocene,integrating inland.information for a better assessment of tectonic activity and.seismogenesis.Multiproxy analyses of the sed.mentary record.constrained.by rad.ometric d.ting allowed.reconstructing event stratigraphy and.linking resed.mented.d.posits to specific earthquakes.Onshore and.offshore d.ta allow to id.ntify large-magnitud. earthquakes in the central Calabrian Arc subd.ction system d.ring the Holocene,with inferred.epicenters located.either along normal faults onshore and.or related.to the slab d.namics.The turbid.te record.reveals 20 major events d.ring the last 10 ka,with sources includ.ng crustal faults in Calabria(i.e.Lakes,Rossano and.Cittanova faults).Analyses of sed.ment samples and.high-resolution seismic reflection images allowed.id.ntification of d.fferent types of resed.mented.d.posits d.ring the last 30–50 ka.The basin-wid. occurrence of three megaturbid.tes/homogenites suggests they are related.to megatsunamis sourced.by far field.earthquakes along the Hellenic Arc.Me

Hyd.ogen prod.ction via water electrolysis d.fines the novel energy vector for achieving a sustainable society.However,the true progress of the given technology is hind.red.by the sluggish and.complex hyd.ogen evolution reaction(HER)occurring at the cathod.c sid. of the system where overpriced.and.scarce Pt-based.electrocatalysts are usually employed.Therefore,efficient platinum group metals(PGMs)-free electrocatalysts to carry out HER with accelerated.kinetics are urgently d.mand.d.In this scenario,molybd.num d.sulfid.(MoS_(2))owing to efficacious structural attributes and.optimum hyd.ogen-bind.ng free energy(ΔG_(H*))is emerging as a reliable alternative to PGMs.However,the performance of MoS_(2)-based.electrocatalysts is still far away from the benchmark performance.The HER activity of MoS_(2)can be improved.by engineering the structural parameters i.e.,d.ping,d.fects ind.cement,mod.lating the electronic structure,stabilizing the 1 T phase,creating nanocomposites,and.altering the morphologies using appropriate fabrication pathways.Here,we have comprehensively reviewed.the majority of the scientific end.avors published.in recent years to uplift the HER activity of MoS_(2)-based.electrocatalysts using d.fferent method..Ad.ancements in the major fabrication strategies includ.ng hyd.othermal synthesis method.,chemical vapor d.position,exfoliation techniques,plasma treatments,chemical method.logies,etc.to tune the structural parameters and.hence their ultimate influence on the electrocatalytic activity in acid.c and.or alkaline med.a have been thoroughly d.scussed.This stud. can provid. encycloped.c insights about the fabrication routes that have been pursued.to improve the HER performance of MoS_(2)-based.electrocatalysts.

Black locust(Robinia pseud.acacia L.),a species native to the eastern North america,was introd.ced.to Europe probably in 1601 and.currently extend. over2.3×10~6 ha.It has become naturalized.in all sub-Med.terranean and.temperate regions rivaling Populus spp.as the second.most planted.broad.eaved.tree species world.id. after Eucalyptus spp.This wid.-spread.ng planting is because black locust is an important multipurpose species,prod.cing wood.fod.er,and.a source of honey as well as bio-oil and.biomass.It is also important for carbon sequestration,soil stabilization and.re-vegetation of land.ills,mining areas and.wasteland.,in biotherapy and.land.caping.In Europe,black locust is d.ought tolerant so grows in areas with annual precipitation as low as 500-550 mm.It tolerates d.y,nutrient poor soils but grows best on d.ep,nutrient-rich,well-d.ained.soils.It is a fast-growing tree and.the height,d.ameter and.volume growth peak before the age of 20.It mostly regenerates vegetatively by root suckers und.r a simple coppice system,which is consid.red.the most cost-effective management system.It also regenerates,but less frequently,by stool sprouts.Its early silviculture in prod.ction forests includ.s release cutting to promote root suckers rather than stool shoots,and.cleaning-respacing to remove low-quality stems,red.ce the number of shoots per stool,and.ad.ust spacing between root suckers.In ad.ition,early,mod.rate and.frequent thinning as well as limited.pruning are carried.out focusing on crop trees.The species is regard.d.as invasive in several European countries and.its range here is expected.to expand.und.r pred.cted.climate changes.
